[8.07] First Test Observations and Measured Parameters of the SMTO

The 10m diameter Heinrich Hertz Telescope (HHT) of the Submillimeter
Telescope Observatory (SMTO), located on Mount
Graham, has entered the phase of astronomical
testing and calibration. After having reached a reflector accuracy of
about 30 microns (see accompanying poster), we have proceeded with the
measurement of a number of characteristics, such as pointing parameters,
tracking behavior, beam parameters and aperture efficiency. Most of
these measurements were done with bolometer systems at wavelengths of
1.2 and 0.35 mm. In the poster we summarize the results of these measurements
and indicate the expected performance parameters of the HHT during the
first few months of astronomical observing. Particular attention will
be drawn to the special features of the telescope design, which enable
the telescope to attain unsurpassed performance for observations in
the shortest submillimeter windows. Examples of observations will be
used to illustrate the status of the facility at the end of 1994,
slightly more than two years after the beginning of the mechanical assembly.
